Preheat oven to 400°F (200°C). Heat oil in large skillet set over medium heat; cook pepper for 3 to 5 minutes or until starting to soften. Stir in KFI Butter Chicken sauce, chicken, black beans and corn; bring to simmer. Cook, stirring frequently, for about 3 minutes or until chicken is heated through.

Toss together Cheddar, mozzarella and Swiss cheese. Spread half of the tortilla chips on parchment paper–lined baking sheet; scatter half of the chicken mixture and half of the cheese mixture on top. Repeat layers.
